 Above 30m, it's a good idea to tune out the grid's XC.  See:

The XL of L1 tunes out the grid's XC for whatever frequency you choose. 
 note -- this is the first step in tuning up such a machine.  .

  Depends on anode V and screen V.  With 7kV and 1kV, you should be 
able to get 2.6 out.

  They provide the best match over a wide frequency range.
